Eigenmann , 1903 |
Moenkhausia is a genus from the family of the true tetras (Characidae). The genre was established in 1903 by Carl H. Eigenmann , who assigned the genre in honor of his friend WJ Moenkhaus. Moenkhausia species are widespread in South America. Especially the brilliant tetra and the roach Moenkhausia are often kept freshwater ornamental fish .
features
The genus combines a large number of very different tetra with relatively high back as well as with elongated, spindle-shaped shape. Moenkhausia species become 3.4 cm to 10 cm long. The sideline is complete (with the exception of Moenkhausia sanctaefilomenae ) and runs straight or only slightly curved downwards. The caudal fin base is scaled like in Hemigrammus , the scales on the caudal fin base are smaller than the scales on the rest of the body. An adipose fin is present. The maxillary is usually occupied by three teeth, which are immediately behind the premaxillary-maxillary junction. Some species are also toothless. In the males of some species, e.g. B. in the brilliant tetra, the dorsal and anal fins are enlarged.
Way of life
Moenkhausia species are schooling fish from the middle water regions. Some species are said to be territorial at times. They do not care for the brood, but release their spawn as free spawners in fine-feathered aquatic plants or directly below the surface of the water.
